Application 'April 2, 1946, Serial No. 659,087 (-01. 19-167) 2 Claims.

This invention relates 'toadjustable roller clearer stop motion attachment for textile drawing frames, the object of the invention being to provide means for automatically stopping the drawing frame rollersv when the cotton wraps.

around or collects onany of the rollers of the drawing frame, thereby insuring against thick and thin places being formed in the sliver being drawn, and at the same time preventing breakage of the rollers and stands, due to the formation of an enlargement on the rollers.

With the foregoing and other objects in-view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a plan view of the device constructed in accordance with the invention, illustrating the device as mounted on a drawing frame.

Figure 2 is a side elevational view thereof.

Referring to the drawings in detail, the reference character 5 indicates a textile drawing frame which is provided with bearings in which the shafts of the draw rollers 6 are mounted, the draw rollers '6 cooperating with the draw rolls 1 that are mounted directly thereabove, to engage the cotton being drawn.

The shafts 8 on which the draw rolls I are mounted, move in the slots 9 which provide bearings for the draw roll shafts.

The device forming the subject matter of the present invention, embodies a frame which is adjustably connected with the slats I that form a part of the drawing frame of the machine.

The reference character I l indicates the main supporting bars of the frame of the attachment, each bar being formed with right-angled ends l2 which are slotted throughout their lengths, to accommodate the securing bolts l3 which extend through the slats l0, securing the main supporting bars to the slats. Nuts I4 are mounted on the inner threaded ends of the bolts [3, and by loosening these nuts, the main bars may be moved vertically, for purposes to be hereinafter more fully described.

The main supporting bars II are formed with elongated openings l which accommodate the screws IS, the heads of the screws 16 contacting with the lower surfaces of the main supporting bars, while the threaded inner ends thereof are cleaning rolls I9.

seated in threaded openings of the brackets. l1 that are also formed with elongated cut-out portions providing bearings for the shafts :lB of the Also adjustably secured to the main supporting bars II, arearms 20, the arms 20 risingfrom the main supporting bars at opposite sides of the frame of the attachment. Secured to these arms 2! are screws 2| that extend throughthe elongated openings 22 of the arms 23, the connection between the screws 21 and arms 23 being such that the arms 23 may pivot thereon. The arms 23 are formed with openings that accommodate the shafts I8 of the cleaner rolls l9, so that vertical movement of the rolls l9 will elevate the outer ends of the arms 23, lowering the inner ends thereof so that the inner ends of the arms 23 will contact with the draw rol-ls directly thereunder.

The reference character 24 indicates a wire which connects with one of the main bars H, the wire 24 being in circuit with the source of electricity supply 25. The wire 26 leads from the source of electricity supply 25, and connects with the solenoid 26'. The circuit to the solenoid is completed through the wire 21, which connects with the textile drawing frame, the wire 21 being connected with the solenoid, as clearly shown by Fig. 2.

The reference character 28 indicates a switch arm which carries the contact member 29 that moves to bridge the wires 30 that lead to the electric driving element of the drawing frame.

Dhus it will be seen that when the rolls l9 move upwardly, the outer ends of the arms 23 move upwardly with the rolls, while the inner ends thereof swing downwardly to contact the metal surfaces of the draw rolls 1, completing the circuit to the solenoid. It follows that when the solenoid is energized, the arm 28 will be drawn to the right, breaking the circuit to the motor or power device of the stop motion mechanism of the apparatus.

The upward movement of the draw rolls will occur when clear waste or loose lint from the sliver collects on the draw rolls 6 to form an enlargement thereon to press the draw rolls 1 upwardly as the rolls rotate to accomplish the drawing operation.

llt might be further stated that the cleaning rolls l9 are covered with woolen material to cause the lint to collect thereon.

In view of the foregoing it is thought that the operation of the mechanism will be clear, and

that a further detailed description of the operation of the device is not necessary.

What is claimed is:

1. The combination with stop motion mechanism of textile drawing frames including a pair of upper and lower draw rolls, one roll of each pair of draw rolls being movable vertically, of a stop motion control mechanism including an attachment frame mounted above the draw rolls adjacent thereto, vertically movable cleaning rolls having shafts mounted within the attachment frame normally contacting with the upper draw roll of each pair of draw rolls removing material therefrom, contact arms having openings adjacent to one of the respective ends thereof in which the shafts of the cleaning rolls are disposed, an electric control circuit connected with the stop motion control mechanism including the attachment frame, contact arms and upper draw rolls, said contact arms having elongated openings, screws extending through the elongated openings and attachment frame pivotally mounting the inner ends of said contact arms on the attachment frame, the free ends of the arms being movable into contact with upper draw rolls upon upward movement of the rolls, completing a circuit operating said stop motion mechanism.

The combination with stop motion mechanism of textile drawing frames including a pair of upper and lower draw rolls, one roll of each pair of draw rolls being movable vertically, of a stop motion control mechanism including an attachment frame mounted above the draw rolls adjacent thereto, brackets extending upwardly from the attachment frame, said brackets having vertical slots, vertically movable cleaning rolls having shafts mounted within the attachment frame normally contacting with the upper draw roll of eachvpair of draw rolls removing material therefrom, the shafts of the cleaning rolls being disposed within said slots, horizontally disposed contact arms having openings adjacent to one of the respective ends thereof in which the shafts of the cleaning rolls are disposed, an electric control circuit connected with the stop motion control mechanism including the attachment frame, contact arms and upper drawing rolls, said contact arms having elongated openings elongated longitudinally of the arms, screws extending through the elongated openings and attachment frame pivotally mounting the inner en-ds'of said contact arms on the attachment frame, the free ends of the arms being movable into contact with upper draw rolls upon upward movement of the rolls, completing a circuit operating said stop motion mechanism.
